ROLLING-BARREL.

Specification of Letters Patent.

Patented June 6, 1911.

To all whom it may concern:

Be it known that we, HERBERT A. JoHN- SON and JOHN W. FoRon, citizens ofthe United States, residing at New Britain, in the county of Hartfordand State of O011- necticut, have invented certain new and usefulImprovements in Rolling-Barrels, of

' barrel proper B is operatively supported in Our invention relates toimprovements in I which the following is a specification.

rolling barrels and particularly as applied to the barrel proper and theobjects of our improvements are simplicity and economy in constructionand. convenience and efficiency in use.

In the accompanying drawings :--Figure 1 is a view of the front end ofour rolling barrel. Fig. 2 is a perspective view of a screen gate, on anenlarged scale. Fig. 3 is a sectional view of the barrel proper on theline w a: of Fig. 1. F ig. 4: is a similar view on the line 3 y ofFig. 1. Fig. 5 is a fragmentary view similar to Fig. 3, the gate beingremoved. Fig. 6 is a view similar to Fig. 2, of a solid gate. Fig. 7 isa side elevation of the rolling barrel shown in Fig. 1.

A is our rolling barrel and comprises the barrel proper B and means ofsupport therefor, and operating mechanism whereby the said barrel properB may be rotated on its axis. The said supporting and operatingmechanism comprises a standard or frame work D having means foroperatively supporting a driving shaft E having a driving pulley Fdriven by a belt G, and means for operatively supporting the said barrelproper B, all of which is ordinary. The operative supporting means maycomprise, as shown, an annular supporting plate or ring I, to which thebarrel proper B is secured by means of bolts 10 and nuts 11, andprovided with an annular rack 12, all supported from the frame work D inan ordinary manner on the end of a shaft supported within the sleeve J,which may be tilted and adjusted to different angular positions by meansof a segmental rack 13, which is connected by gearing K with a crank andhandle 15. For operating the said barrel proper B a gear H mounted on ahorizontal shaft E meshes with the said annular gear 12. The said barrelproper B comprises a generally cylindrical shell like structure, theexterior wall 16 preferably being divergent from the front to the rear,and provided outer wall 16 and screws 29. Centrally with a closed bottom17. The said exterior wall 16 and bottom 17 may be made of wood ofconventional form, and held together by means of hoops 18. The saidbottom 17 has bolt holes 19 suitable for receiving bolts whereby thesaid bottom 17 is secured to the said standard or frame work D and thesaid the manner described. At the front end 20 of the said barrel properB we provide a dam 21 comprising an, annular plate the outer peripheryof which is a fit for the said front end 20 and is rigidly secured inplace in an ordinary manner, as by the pressure of the said hoops 18onthe said side fir t e said dam 21 is provided with a hole 22, shown ascircular, which serves as a hand hole, whereby access may be obtained tothe interior of the said barrel proper B, as for the purpose ofinserting or removing stock to be operated upon, abrasive or polishingmaterial, and water. The said annular dam 21 has on one side an openingor slot 23, shown as extending across the same and which opening haslateral walls 24 that are parallel with the radius passing through thecenter of the said opening or slot 23 and the dam is provided with agate 25 which fits the said side walls 24 and slot 23 and when in normalposition in said slot serves to close the same and thereby complete theannular formation of the said dam 21. Guide plates 26 secured by rivets27 to the said dam 21 overhang the said opening or slot 23, there beingone such plate 26 on the front and an other on the back of each of thesaid lateral walls 24:, thereby forming on each side a grooved channel28 for guiding the said gate 25 when being inserted in place in the saiddam 21 or removed therefrom and to hold the same against displacementtoward the front or back. The said gate is held in place againstdisplacement radially by means of a catch L comprising as shown aswinging hook 31 secured to the said gate 25 by the screw eye 32 and thescrew eye 33 screwed into the said barrel proper B, and in such positionas to register and engage with the said hook 31 when in normal positionwith the gate closed.

As described our rolling barrel has means for being rotated and onaccount of the hand hole has ready means of access to the interior; andon account of the provision of the gate the same may be readily emptiedentirely of its contents; and furthermore, and in combination with thefeatures mentioned it is possible to operate our barrel at such anadjusted position of its axis that the lower or bottom portion of thebarrel proper B will be essentially horizontal during normal conditionsof operation. This latter feature we find facilitates a proper andeffective distribution and intermingling of the stock or goods operatedupon and the abrasive or operative materials, which latter may includehardened steel balls and a supply of water.

In Fig. 2 is shown a screen gate M which may replace the solid gate L.

It is apparent that some changes from the specific construction hereindisclosed may be made and therefore we do not wish to be understood aslimiting ourselves to the precise form of construction shown anddescribed, but desire the liberty to make such changes, in working ourinvention, as may fairly come within the spirit and scope of the same.

We claim as our invention 2- A rolling barrel comprising a barrel properand means for operatively supporting the same, the said barrel propercomprising a shell-like structure provided at one end with an annulardam having a central hand hole and the said means comprising means forvarying the inclination of the aXis of revolution of the said barrelproper, and the said annular dam provided with a gateway extendingradially across one side of the same and a gate therefor.
